T0 ALL WI-IOM- IT MAY'CONCERN: l Y

Be it known that'I, GEORGE W. TRIMBLE, of Bloomsburg, in the county of Columbia, and State of Pennsylvania, have invented a new and useful Improvement in Mining and Furnace-Lamps; and do hereby declare that the following is a. full, clear, and exact description 'of the construction and operation of the same, reference being had to the accompanying drawings,makng a part Vot' this specification, in which- Figure 1 is a side elevation. A i

Figures 2, 3, and 4 are `views in detail of the feeding-device of the lamp.

'The nature of my invention consists in providing lthe tube or spout of the lamp with a simple and novel device for feeding the wick to the flame, instead of pushing it out of the tube by striking the bottom of the lamp on something, whichin' ashort time so injures the lamp as to cause it to leak, andwhere many are used, considerable expense is entailed for repairing, which I obviate by the device, as will hereinafterbeishown.

y '.lo enable anyone s lgilled 4inthe art to mal-ie and use my invention, I will proceed to describe its constructi'onnrid operation.` I

A is the lamp, B is the tube orspout, C is the wick. The device consstsof an elongated piece of tin, a, tapering on b oth sides towardl'the end, where it is rounded. 'lhe other end isicut inwardlyto the centre at a suitable angle, and thence cut inwardly again to a slot, b, which is to receive the anges ofthe thumb-slide for fastening it thereto. V This piece is then bent around, and assumes the form seen in figs. 1 and 2. An elongated slot is maderin thetube, with small strips of tin soldered around the edges thereof, to give the proper sti'ness, for the slide, which will workthcrein against the edges. A`pl'ate, D, having a'corresponrling slot, c, is placed over the strips and soldered on to the tube. is the thumb-slide, provided with a guide-bar, d, which is inserted in an opening of the cross-piece c, soldered on to' the plate at its lower end. The flanges, g, of the Slide me inserted through the slots of the platel and tube, and thence through the device, where they are bent over in 'opposite directions, und made fast to the under sides of the device.

Operation: By working the thumb-slide upand down on the plate of the tube, the angular pointed ends or sides of the device, which almost entirely encompass the wick, shove it forward, and thus feed it to the flame.

Having thusfully described' my invention, what I claim therein as new, and desire to secure by Letters Patent, isi Providing the tube or spout of a mining and furnace-lamp with a feed-device for the wick, substantially as described.

GEORGE W. TRIMBLE.
